In October 2012, Felix Baumgartner leapt from a balloon floating 24-miles high and fell to Earth, breaking the sound barrier on the way down. Now, newly released footage shows in unprecedented detail what Baumgartner saw on his record-breaking descent.

"I wish you could see what I can see," said Baumgartner, just seconds before stepping cooly from a pod suspended 128,100 feet above the ground. "Sometimes, you have to get up really high to understand how small you are."

Consider Baumgartner's wish granted. You'll want to watch this in full screen, HD, with headphones if you have some on hand. The action starts around the 1:40 mark. Be Advised: The whole video has an understandably vertiginous quality about it, but things get especially intense around the 5:20 mark, where Baumgartner, shortly after breaking the sound barrier, loses control of his free-fall and begins to spin. He manages to stabilize himself, but not before almost passing out. It's a nauseating view, even for armchair-spacejumpers, so be careful not to lose your lunch.
